4-3 with a lot of the Seattle version of the 4-3 Under which incorporates the LEO.

It's my guess that we'll see a lot of different looks next year with a lot of different personnel and personnel placement, but that the primary look will be the aforementioned version of the 4-3 Under.

Owen Hart is a perfect fit as LEO in a 4-3 Under as is Andre Branch. I also like Jason Babin as a LEO which is why I could see us retaining him for one year while Branch and possibly a draft selection continue to develop and rotate in._________________

I guess all that is true. I wouldnt mind taking a swing for the fences if it means he turns into a JPP-Miller type where he is a force to be reckon with, even if the bust potential is there._________________

Going off of this, we'd need a new LEO/SLB, and a Barkevious Mingo or Jamie Collins could fill that role, with Mingo being better. DeVonte Holloman or Khaseem Greene to replace Poz. This is also assuming we keep Daryl Smith and Terrancce Knighton._________________

Is Babin the Leo in this front? Also why isn't Poz in the middle? With that kind of formation we really need to load up on DT's, because behind those three we have no depth, and one of them is a FA._________________2nd place in Jaguars forum USJJC 2012

Yes, he is the LEO. Poz isn't in the middle because he isn't our fastest backer whom can cover the field, Daryl is, and here, he [Poz] can contain the outside. Agree, we need at least one more 2-gap line plugger, similar to an Alan Brach/Brandon Mebane. Tyson is the prototypical 5T in this case, and can contain the edge._________________

I don't think Babin is a starter, especially not over Mincey._________________GopherWrestler knows his way around a sig...
"We're not trying to win the AFC South, we're trying to own the AFC South." - Gus Bradley

The modified 4-3 Under that Gus Bradley ran in Seattle isn't really "basically a 3-4"

It's still a 4-3 front, but it has a mix of 3-4 and 4-3 concepts. I also suspect that we'll run a variety of fronts with multiple concepts.

This is not a depth chart, but a list of prominent guys we have and where they could fit

LEO: Jason Babin, Andre Branch

DT (3T): C.J. Mosley, Tyson Alualu, D'Anthony Smith

DT (not really a NT, but sized as a NT and moves around among 3T, 0T, 1T - should be big guy who can also get pass penetration - Knighton would fit here, but not sold he will be back): Jeris Pendleton - could have Mosley and Alualu as two interior DTs again if necessary

RE (5T): Tyson Alualu, Austen Lane, MAYBE Jeremy Mincey

To be honest, I see Mincey as a bit of a misfit, but we should run enough normal base 4-3 with him at either LE or RE to where it won't matter. He could also do well enough at the 5T spot in the 4-3 Under considering how well he is against the run to begin with and his size (~280 IIRC). I could see Lane playing some LEO too, but I think with Babin, Branch, and possibly another LEO selected in the draft that there's no reason to do that unless we don't select one in the draft.

If Branch improves or we get someone with a lot of upside in the draft (or we keep Babin and he is our primary LEO) then we could see quite of improvement in pass rushing assuming health is not a concern (especially for Lane who has made strides).

I would prefer to add one more LEO in the draft because I want to be able to rotate guys in and out and move them around. That versatility, depth, and ability to stay fresh can go a long way. We'd have 5 at least solid options at DE (Babin, Branch, Draft Pick, Lane, Mincey) and 6 if you count Alualu when he is kicked out to that 5T spot. I don't know if Selvie or Chick will be back so I did not include them. Chick and Davis are LEO options and Selvie is a bit of a misfit like Mincey.

MAIN difference to keep in mind: rather than a 4 man front with a 5th player as the LEO (as demonstrated in that link IIRC), it is a 4 man front with one of the 4 as the LEO. The LEO would generally be a pass rushing linebacker in a 3-4 or is a 4-3 DE that is best suited at the 9T. Having Babin play LEO would allow him to play at the 9T position where he succeeds without running the 9-wide which is a system that leaves you susceptible to the run. With the modified 4-3 Under, that susceptibility to the run is accounted for with the bigger DT inside (in Seattle, this was Alan Branch) and a bigger DE in the 5T position or just one that is good against the run (in Seattle, this was Red Bryant - here, it would be Alualu, Lane, Mincey, etc.). As well, in the modified 4-3 Under, the extra LB is allowed to count for the run as there is now a 4-man front as opposed to 4 and the LB playing up front.

I hope that cleared a lot of it up. I tried to explain it as best as I could at this moment.

Why would Poz move to OLB? He'd have to be in coverage more. Lining up in man against TEs.

Daryl Smith should stay at SLB because he is the only one who I feel comfortable with covering a TE.

Half of it is that he isn't fast enough to cover the middle is this system...on top of that MLB typically plays more coverage regardless and the OLB is contain/bracket pending over/under/bear._________________

I didn't think the MLB was in coverage as much for this scheme. Mostly playing man against the rb in man(sometimes WLB would). Safeties would come down to cover 2nd tightends or 3rd receivers._________________
